here are some small bugs
Maybe you’ve come across some bugs like this, which often happens because of wrong coding
1. ErrorCode: Type ‘yourEnum’ has no member ‘allCases’
The solution is to use CaseIterable
that automatically generates an array property of all cases in an enum
// Error Codeenum ListSection: Int {
case registered = 0
case login = 1
case biometric = 2
}print(ListSection.allCases.count) // error here// Solutionenum ListSection: Int, CaseIterable {
case registered = 0
case login = 1
case biomatric = 2
}print(ListSection.allCases.count) // 3
2. initializer without initializing all stored properties
I try to change a property from let to var but still not working and get this error “Return from initializer without initializing all stored properties”. I tried to check the comparison with other `init` but couldn’t find a solution. I’m trying to find out again. What is wrong, finally I found the error because the variable “accountEmail” and “accountName” if you create “init “ you need to give an optional value to a variable not to call in “init”.
3. Error: validation failed: Couldn’t parse property list because the input data was in an invalid format
When create a Localizable. strings file and found this error on the top file, I don’t know where the error is, so you can try this for how to know where the error.
- Right-click the strings file and
- Then Open as/ASCII property list.
After you click that popup will show where the error line and what makes an error on this page, and then a popup will show like this.
4. Type of expression is ambiguous without more context
I get some error when write code like this
userWorker.getUserProfile(username: username) { [weak self] result in // error in here
.
.
.
}
to solve that error just remove `weak`
userWorker.getUserProfile(username: username) { [self] result in
.
.
.
}
