For those new to message boards please try to follow a few simple rules when posting your question.- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
cheers

Hi everyone,
I'm looking for an iOS app that can control Arduino IoT pins. Any recommendations for apps that are user-friendly and reliable?
Thanks!

Hi everyone, I hope you are doing well.
I'm working on a project that involves Arduino microcontroller and I would like to develop an app that can control such devices. I'm using wifi as communication protocol.
By any chance do you have any examples (simple source code) that I can use as a reference to make communication between an IOS app and Arduino?
Thanks in advance.
Regards

Hello
Friends, I am a newbie
I want to write a program that receives several inputs from the user, puts the inputs in an array, and by selecting a button, displays these inputs one by one in the message box, that is, every time I click OK on the message box, it displays the second input And it will continue like this until the entries entered by the user are finished, it is very urgent, please help me

Not Enough Storage
This iPhone cannot be backed upbecause there is not enough iCloudstorage available.
You can manage your storage in Settings.

This is a software development site, not Apple support.
Read the error message, and it's obvious that it has nothing to with software development, and everything to do with the configuration of your Apple iClod account which we can do nothign about, even if we wanted to.
A trivial google would have found you the official solution: If you can't back up to iCloud - Apple Support[^]
In future, please do at least basic research yourself and not waste your time or ours ... and post support questions on support sites!

Hi
Just started on a test project to see how to access data on the company network in a mobile app.
Short I have some data logged into a SQL table that I want to display/access on a phone (both Android and iPhone).
So inspired from something I worked on some years ago and some google'ing I made a WCF service and are trying to access it in Xamarin.
BUT... I am now in doubt if what I am doing is the best way to do it?
I have just read that WCF is dead and I am not sure if Xamarin is also dead.
So before using to much time running in the wrong direction...
Is WCF the best way to go, or what should I use?
Same with Xamarin - better alternative?
I hope this is not to stupid a question that have been asked a zillion times and I just havn't stumpled across it....
Thanks in advance
//David

WCF isn't dead as such - there's even an open-source port for .NET Core/5/6/…[^] which is being actively developed - but I believe all the "cool kids" are using gRPC[^] these days.
Similarly, whilst Xamarin isn't going away any time soon, the next MS bandwagon seems to be .NET MAUI[^].

WEB API is a better choice for simpler, lightweight services. WEB API can use any text format including XML and is faster than WCF. WEB API can be used to create full-blown REST Services.

Xamarin is a tool in the Cross-Platform Mobile Development and most of the time I have used this one only. It is also the faster way to build iOS, Android, and Windows apps. So, I would prefer this mode only.

If you want to replace WCF then the best option left for you is gRPC and Web API. The WCF is more adaptable to work for multiple software.

I want to use AES-GCM encryption of a plaintext with 'key' only. The 'key' will be received from backend (.net), in webservice response. The same key will be used later in backend as well to decrypt the encrypted value.
I have used extension as follwoing
To generate string to Symetric key
extension SymmetricKey {
init(string keyString: String, size: SymmetricKeySize = .bits256) throws {
guard var keyData = keyString.data(using: .utf8) else {
print("Could not create base64 encoded Data from String.")
throw CryptoKitError.incorrectParameterSize
}
let keySizeBytes = size.bitCount / 8
keyData = keyData.subdata(in: 0..<keySizeBytes)
guard keyData.count >= keySizeBytes else { throw CryptoKitError.incorrectKeySize }
self.init(data: keyData)
} }
Encryption & Decryption code snipet:
func aesgcmEncryptDecrypt() {
let str : String = "FwhXRYJ$xLf?^Kh6_&YfTJ%RuG+EqcTY"
var key : SymmetricKey = SymmetricKey(size: .bits256)
do{
key = try SymmetricKey(string: str)
}catch{
}
let plain = "HOW ARE YOU?"
let nonce = try! AES.GCM.Nonce(data: Data(base64Encoded: "fv1nixTVoYpSvpdA")!)
let tag = Data(base64Encoded: "e1eIgoB4+lA/j3KDHhY4BQ==")!
let sealedBox = try! AES.GCM.seal(plain.data(using: .utf8)!, using: key,
nonce: nonce, authenticating: tag)
let sealedBoxRestored = try! AES.GCM.SealedBox(combined: sealedBox.combined!)
let decrypted = try! AES.GCM.open(sealedBoxRestored, using: key,
authenticating: tag)
Swift.print("Combined:\n\(sealedBox.combined!.base64EncodedString())\n")
Swift.print("Cipher:\n\(sealedBox.ciphertext.base64EncodedString())\n")
Swift.print("Nonce:\n\(nonce.withUnsafeBytes {
Data(Array($0)).base64EncodedString() })\n")
Swift.print("Tag:\n\(tag.base64EncodedString())\n")
Swift.print("Decrypted:\n\(String(data: decrypted, encoding: .utf8)!)\n")
}
Our(generated from this code & .Net code) encrypted text is not matching. Anyone can help me, what I am doing wrong, detailing will be more helpful. Basically I was looking for saloution in Objective-C but I did not get any supported library for Objective-C.

how to find macos offset value
macos 10.15.1 = 0xA21F
how to find other macos systems. some one tell me
|
|
|
|
|
|
var offsetHandlerDeliveryReceipt = 0xA21F; # this is offset value
var deliveryReceiptHandlerAddr = iMessageBase.add(offsetHandlerDeliveryReceipt);
send("Hooking -[MessageServiceSession handler:messageIDDelivered:...] @ " + deliveryReceiptHandlerAddr);
Interceptor.attach(deliveryReceiptHandlerAddr, {
onEnter: function(args) {
send("DELIVERY_RECEIPT");

Is the functionality of IOS better than android or not?
|
|
|
|
|
Yes and no. But the question is fairly meaningless. What works well for one user may not be the same for another.
|
|
|
|
|
Of course yes, there is a big difference between the Android app and IOS app because of their functionality and many other things.
|
|
|
|
|
yes of its reliability and smoothness.
