For setting up n number of lines of Text in swiftUI we can use .lineLimit(.. function which takes arguments as number of lines.
#For iOS 15 & Below :
we have to set .fixedSize(horizontal: false, vertical: true)
& .lineLimit(2)
Text("A two lines TextABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890 All alphabates")
.fixedSize(horizontal: false, vertical: true)
.lineLimit(2)
# For iOS 16 onwards
Text("A two lines TextABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890 All alphabates")
.lineLimit(2, reservesSpace: true)
