I'm trying to enable the "Apple Arcade Operations" capability, and it seems to be under "Additional Capabilities" tab: However I can't see that tab in my identifiers: Does anyone know how to enable such tab? Thanks in advance!

Hi everyone, after Catalina upgrade this simple grep call from a Mac app started to fail, while running it from Xcode I'm getting this error in the Xcode console: ".../file.txt: Operation not permitted".It's kind of obvious that this is because of the security changes in Catalina, I've been looking for a while, but haven't been able to make it work, any idea on how to solve it?Thanks in advance, this is the code I'm using:- (void)simpleGrep{ NSPipe *pipe = [NSPipe pipe]; NSFileHandle *file = pipe.fileHandleForReading; NSTask *task = [[NSTask alloc] init]; task.launchPath = @"/usr/bin/grep"; task.arguments = @[@"word", @"/Users/xxxxxxx/Documents/SampleFiles/file.txt"]; task.standardOutput = pipe; [task launch]; NSData *data = [file readDataToEndOfFile]; [file closeFile]; NSString *output = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; NSLog (@"Finish with output: %@", output); }The NSLog prints "Finish with output: (null)".
