"Unable to simultaneously satisfy constraints." warning when adding a Navigation title.

Forums > 100 Days of SwiftUI

Hello !

I am currently in day 48, i was following this video that explained fetching data from an API. Later I added a navigation view and a title just so that it looks a little bit better.

this is the code :

 var body: some View {
    NavigationView {
       List(results, id: \.trackId) { item in
          VStack (alignment: .leading) {
        .navigationTitle("Taylor Swift Songs")

       .task {
          await loadData()


Then this thing started appearing :

"[LayoutConstraints] Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( "<NSLayoutConstraint:0x600003f7c2d0 'BIB_Trailing_CB_Leading' H:[_UIModernBarButton:0x7fc8859139b0]-(6)-[_UIModernBarButton:0x7fc885a0de10'Taylor Swift Songs'] (active)>", .. "

and it goes on...

I noticed that i always have this warning whenever i add a navigation title. commenting the navigation title stops this warning. (Noticed the warning in previous projects but didn't know the exact reason for it.)

Tried Ipod touch & Iphone 11 simulators.

What is the reason for this warning / error in the log area and how to fix it ? And should i be worried in the first place?

I had the same problem when working on Project 5 on day 30. I fixed it by adding the following modifier on the Navigation view itself
