Uglify Doesn't seem to work

Bắt đầu bằng cách tái hiện sự cố với các lệnh được báo cáo tns run ios --release --env.uglify và tns build android --release --env.uglify, sử dụng các phiên bản NativeScript và plugin được liệt kê. Theo dõi điểm vào của quá trình uglification của release build và so sánh đầu ra được tạo trên cả hai nền tảng; được coi là hoàn tất khi đầu ra release không còn dễ đọc và hành vi đã được xác minh cho thiết lập được báo cáo.

When I ran tns run ios --release --env.uglify or tns build android --release --env.uglify it doesn't seem to Uglify the code at all, I can see the source code and it's readable. Am I doing this wrong somehow?

My app is written with NativeScript core and TypeScript.
My environment:
