1. 问题背景 在SwiftUI中,使用ForEach循环遍历一个范围(range)时,如果范围的上限不是一个编译时常量(即编译时就能确定其值),编译器会抛出一个警告:“Non-constant range: argument must be an integer literal”。这个警告主要出现在Xcode更新后,特别是在处理动态数据时。 2. 警告原因 这个警告的出现是因为ForEac...

You have attempted to declare a constant as a class, structure, or array type, or as a type parameter defined by a containing generic type. Constants must be of an intrinsic type (Boolean, Byte, Date, Decimal, Double, Integer, Long, Object, SByte, Short, ...
1） T = new String[2]; // 不允许，T是常量，不能改变其取值 2） T[0] = "123"; // 允许，因为数组成员取值并未被限定为不可改变（即不是常量）所以，你在switch（）中使用 T[i] 作为case值就会引发编译错误“case expressions must be constant expressions ”。final...
java报错:An enum switch case label must be the unqualified name of an enumeration constant 报错:An enum switch case label must be the unqualified name of an enumeration constant 大意就是“枚举的switch case标签必须是枚举常量的非限定名称”。 改成这样就好了: 参考博文:http://blog.sina.com.cn/s...
datasort is defined to be an array of constant integer values, so the function can read the elements of the array, but it can't change them. Mar 24, 2014 at 3:08am kdeng(13) Ok I fixed it by changing datasort to just a int and not a constant so it works now. ...
The msb_base_expr and lsb_base_expr shall be integer expressions, and the width_expr shall be a positive constant integer expression. Each of these expressions shall be evaluated in a self-determined context. The lsb_base_expr and msb_base_expr can vary at run time. Click to expand... ...
