Open ButtonBarPagerTabStripViewController.swift file.
In ButtonBarPagerTabStripViewController class, remove UICollectionViewDelegate protocol and implement UICollectionViewDelegateFlowLayout protocol.

First question, did you call settings.style change before super.viewDidLoad()?
You should call settings.style.* before super.viewDidLoad()
And What's your XCode version?

[ahmedsafadii]

yeah i did and the xcode version is 9

[LifetimeCode]

After your super.viewDidLoad(), add this:

        buttonBarItemSpec = ButtonBarItemSpec.cellClass(width: { _ -> CGFloat in
            return 150  // <-- Your desired width
        })

[ahmedsafadii]

[koko-js478]
