I am making application where I use navigation link to navigate from bottom menu to other views, and there is a problem when I change view a few times because views start stacking and when I set navigationBarBackButtonHidden(false) I can see on left side a lot of back button. This generate big problem because after changing views I got warning Abnormal number of gesture recognizer dependencies: 100. System performance may be affected. Please investigate reducing gesture recognizers and/or their dependencies. And after some more changes everything from screen is pushed down back button. Is there any solution to close previous view from we came?
There is code:

I am making app which one of functionality is register user with firebase, but sometime when I register user I got app crash but user is added into db.
I am getting error like this: EXC_BAD_ACCESS (code=2, address=0x2600000000) or adres = 0x10 which mean the is some memory leak but when I use instrumental leak every thing is ok.
Second weird thing is that when I use instrumental leak I am not getting error (I added something like 40 users) but when I close instrumental and rebuilt I got crash in max 3 attempts.
