I am trying to debug an IOS application developed in Objective C. When using messages with NSLog or print instructions, they are ignored and my console is always empty.

Set breakpoints to verify if your app actually executes that code. Also, make sure there's not active filter in the console, and that it's set to show All Output. – Gereon Apr 16 '20 at 19:23

@Gereon thanks for answering, I did check both of them. The code is executing and I can try my app on the iPhone. But the console shows just few logs from other components. BTW, I am maintaining an application that I didn't develop, and I am still learning Objective C – Ali HAMDI Apr 16 '20 at 19:39

So does the execution halt at your breakpoints? If so, you won't need NSLog anymore. – Gereon Apr 16 '20 at 20:14

My project is composed of two modules , one in Swift and the other one (that I have problem with) is on Objective C When I start debugging, code is stopped in the breakpoints in Swift part, but it does nothing in Objective C part. I tried to add NSLog to my code but didn't get output in the console. – Ali HAMDI Apr 16 '20 at 20:19

So set a breakpoint at a place where your Swift code calls into ObjC. Single-step from there. What happens? – Gereon Apr 16 '20 at 20:36

Unfortunately, bow modules are not related. the main application is built with Swift, the share extension is built with Objective C. I am able to debug the main application, but I am not able to debug nor to print logs for the share extension. – Ali HAMDI Apr 16 '20 at 20:43

It seems that I was doing things wrong, Debugger does not attach automatically to debugger, we need to attach it manually as answered in How to debug ios share extension?
