Font Size Changes in iOS unexpectedly - ios

Question

All
I'm new to iOS and SwiftUI (2 months). I'm struggling to understand the following behavior and hope someone can point me as to how I can diagnose.
I have this code successfully generating this view in the preview provider
however when I run it on a device or in the simulator the fonts change (happens for system images also) to look more like this (scaled up).
The view below is rendered inside of a very generic tabview - I cant fathom it at all and could use some guidance.
Thanks

var body: some View {
VStack(spacing: 0.0) {
HStack(alignment: .top){
Text(player.firstName)
.bold()
Text(player.lastName)
.bold()
}
.font(.title)
HStack {
Image(uiImage: UIImage(data: player.playerPhoto) ?? UIImage())
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: /*#START_MENU_TOKEN#*/100/*#END_MENU_TOKEN#*/, height: 100)
.clipShape(Circle())
.overlay(Circle().stroke(Color.purple, lineWidth: 4.0))
Spacer()
VStack {
Text("lifetime averages")
.font(.body)
.foregroundColor(Color.gray)
HStack {
Spacer()
VStack {
Text("Batting")
.font(.title2)
.bold()
Text("\(battingAverage, specifier: "%.3f")")
}
.padding(.leading)
if isPitcher {
Spacer()
VStack {
Text("ERA")
.font(.title2)
.bold()
Text("\(earnedRunAverage, specifier: "%.2f")")
}
.padding(.trailing)
Spacer()
}
}
}
Spacer()
}
HStack {
VStack {
Text("\(noTeams)")
.font(.headline)
Text("teams")
.font(.subheadline)
.foregroundColor(Color.gray)
}
.padding(.leading, 10)
Spacer()
VStack {
Text("\(noSeasons)")
.font(.headline)
Text("seasons")
.font(.subheadline)
.foregroundColor(Color.gray)
}
Spacer()
VStack {
Text("\(noGames)")
.font(.headline)
Text("games")
.font(.subheadline)
.foregroundColor(Color.gray)
}.padding(.trailing, 10)
}
HStack{
Spacer()
Text("All Lifetime Stats >")
.font(.callout)
.foregroundColor(Color.blue)
}
}
.frame(width: 350, height: 200, alignment: /*#START_MENU_TOKEN#*/.center/*#END_MENU_TOKEN#*/)
}

Your code does not specify a .font(...) for those two Text elements.
Is it possible you have set the default font somewhere else?
I can reproduce what you're getting by doing this (using PlayerView as a stand-alone view, not in a table).
If using UIKit App Delegate, in willConnectTo session:
let contentView = PlayerView()
.font(.largeTitle)
or, if using SwiftUI App:
#main
struct TestApp: App {
var body: some Scene {
WindowGroup {
PlayerView()
.font(.largeTitle)
}
}
}
