Make sure you have nothing else such as QuickTime running at the same time. Otherwise it gets stuck waiting for a lock. Also, make sure the screen is on.

commented

i'm sure there is no other app running at same time except ios_minicap terminal and safari

Hi,
I have encountered similar problem.
I have tried several devices, iphone 6(10.3.3), iphone 5s(10.3.3), iphone 8(11.3.1).
The result is that while using iphone 8(11.3.1), I cannot get any screen img on browser.

I just doubt that some compatibility issues come with iOS 11.

Thanks and look for help.

=========================================================
Updated:
Another devices tried. Both iphone X(11.2.1) and iphone 8(11.2.1) work well.
It seems some issues in iOS 11.3.1。

commented

my iPad Air 2 (iOS 11.2.6) has issues too
how about iOS 11.4 ?

commented

when it stuck and can not get banner. lock the screen and then unlock the screen. then it can get the banner. This operation works for me.

Seems on mojave(10.14) the situation more strange - after disaplay UDID it will crash, leaving a Abort trap: 6.
After tried rerun in lldb, a more detail log appears after the abort line:

[access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

But I don't know how to embed info.plist to a CLI standalone. Have tried LDFLAGS sectcreate method and seems that does not helps, anything same as before.
