Would love to use Swift Charts framework. But I still need to support older iOS versions. Do I need create custom chart solution for iOS15 or any chance SwiftCharts will be backward compatible?
Will Swift Charts be available on iOS 15?
I'd love it to be supported on iOS 15 as well, but unless we hear otherwise, I'm afraid we have to assume it won't be available on iOS 15. Which is a real shame, for those of us developing chart-heavy apps that need to support old versions (due to mandates from those in positions above us).
But I'd love to be wrong.
I attended WWDC22 and I was able to ask someone from the SwiftUI team regarding this. They said that Swift Charts will only be available on iOS 16 and that there are good third party libraries on github which support iOS 15 and below. They didn't specify which ones specifically but I think https://github.com/willdale/SwiftUICharts or https://github.com/AppPear/ChartView would be your best bet.
