Increase size of tab bar item icons in SwiftUI
You can directly use font size like that (tested in Xcode 11.3).
Please note that only works for symbol images (SF Symbols or . custom SVG symbols), it doesn't work for bitmap images.
YourView() .tabItem { Image(systemName: "heart").font(.system(size: 26)) Text("Offers") }
You can create custom tabView to achieve custom height
attached screen shot showing the result of custom tabview which is inspired from this Gist
