How can you view the APN push token value in Xcode 11? (Its no longer displayed fully as a string when logged)

With XCode 11 I am no longer able to view the full value for a push token. Here's some example code to illustrate:



  func pushRegistry(_ registry: PKPushRegistry, didUpdate credentials: PKPushCredentials, for type: PKPushType)
    {
        var method1 = NSString(format: "%@", credentials.token as CVarArg) as String
        print("method1: \(method1)")
       
        method1 = method1.replacingOccurrences(of: " ", with: "")
        method1 = method1.replacingOccurrences(of: "<", with: "")
        method1 = method1.replacingOccurrences(of: ">", with: "")
        print("method1 again: \(method1)")
       
        let method2 = String(decoding: credentials.token, as: UTF8.self)
        print("method2: \(String(describing: method2))")
       
        let method3 = credentials.token.description as String
        print("method3: \(method3)")




However when the above code is run with Xcode 11, this is the output:



    method1: {length = 32, bytes = 0x5b3f44e0 6d2c5ee5 5252d3db f5bb915b ... 12844aeb 13259e7e }
    method1 again: {length=32,bytes=0x5b3f44e06d2c5ee55252d3dbf5bb915b...12844aeb13259e7e}
    method2: [?D�m,^�RR�����[� � ��>� �J� %�~
    method3: 32 bytes


In previous versions of Xcode, method1 would be logged/viewable as something like this:



44154da73234500153106883ffc1071fa59c0d24f1a1d29ea70871e5aa8dbb41



But now its this:



    0x5b3f44e06d2c5ee55252d3dbf5bb915b...12844aeb13259e7e



There is ... in the middle of it.




How can I just log/interactively view the contents of credentials.token with Xcode 11?



I want to copy/paste the value into a php script to manually send push message to the app for testing purposes.

Hi, you can use the following method:return [tokenString copy];

- (void)pushRegistry:(nonnull PKPushRegistry *)registry didUpdatePushCredentials:(nonnull PKPushCredentials *)pushCredentials forType:(nonnull PKPushType)type {
    if ([pushCredentials.token length] == 0){
        NSLog(@"PUSH CREDENTIALS TOKEN IS NULL");
        return;
    }
    
    NSLog(@"VOIP PUSH TOKEN OBTAINED: %@", [self stringFromVOIPTokenData:pushCredentials.token]);
}


- (NSString *)stringFromVOIPTokenData:(NSData *)tokenData {
    const char *data = [tokenData bytes];
    NSMutableString *tokenString = [NSMutableString string];
    for (int i = 0; i < [tokenData length]; i++) {
        [tokenString appendFormat:@"%02.2hhx", data[i]];
    }
    
    return [tokenString copy];
}
