Given the infamous < NSLayoutConstraint:0x1c809d970 UIView:0x11fe288b0.height == 16 (active)> & co from the autolayout engine
what's the brave new swiftly world way to print an object of UIView class by a hex pointer value?
(lldb) p *((UIView*)0x11fe288b0)
error: :3:12: error: expected ',' separator *((UIView*)0x11fe288b0) ^ ,
(lldb) po *((UIView*)0x11fe288b0)
error: :3:12: error: expected ',' separator *((UIView*)0x11fe288b0) ^ ,
(lldb) expr *((UIView*)0x11fe288b0)
error: :3:12: error: expected ',' separator *((UIView*)0x11fe288b0) ^ ,
This is in xcode 10.3 and 11 beta 3
UPD:
(lldb) p *((UIView*)0x11fe288b0)
worked at first in xcode 11 beta 5, now it ceased to work: this might have been fixed in beta 5 but possibly that fix got clobbered when I went back to xcode 10.3 that "installed additional components"
UPD2: this seems to be a duplicate of Xcode debugger (lldb) get object description from memory address
If the problem is just layout constraints, the simplest solution is to give your constraint a string identifier. You can do that in code or in the storyboard. Makes debugging constraints really easy; the identifier appears in quotes first thing in the debug output:
[LayoutConstraints] Unable to simultaneously satisfy constraints.
(
"<NSLayoutConstraint:0x600003af86e0 'getStartedBad' ... >",
"<NSLayoutConstraint:0x600003af8730 'getStartedTop' ... >"
)
If the question is about a UIView for which you have only the address, you can send messages to it like this:
(lldb) expr -l objc -O -- [(UIView*)0x11fe288b0 layer]
(Yes, you have to talk Objective-C to it, but I don't think there's any other way.)
