Hipo Assignment App (Internship)

This project was made within "Hipo Summer Internship Application".

⚠️ When using the application in the simulator, UIImagePickerController will open slowly. To avoid this problem, test on a real device. Stack Overflow

Data Storage

UserDefaults and CoreData were used to store data in the project. UserDefaults was used to control the first launch of the application. CoreData is used to store Team and Member information. There is a one-to-many relationship between Team and Member. There is a one-to-one relationship between Member and Hipo.

CoreData Model

CRUD in CoreData for Member

Create

func createMember(image: UIImage?, teamId: Int16, name: String, github: String, age: Int16, location: String, position: String, yearsInHipo: Int16) -> MemberCDModel {
    let member = MemberCDModel(context: context)
    
    if let image = image {
        member.imageData = image.jpegData(compressionQuality: 0.5)
    }
    member.team = fetchTeam(id: teamId)
    member.name = name
    member.github = github
    member.age = age
    member.location = location
    
    let hipo = HipoCDModel(context: context)
    hipo.position = position
    hipo.yearsInHipo = yearsInHipo
    
    member.hipo = hipo
    
    saveContext()
    
    return member
}

Read

func fetchMembers() -> [MemberCDModel] {
    let fetchRequest: NSFetchRequest<MemberCDModel> = MemberCDModel.fetchRequest()
    do {
        let members = try context.fetch(fetchRequest)
        return members
    } catch let fetchErr {
        print("Failed to fetch:", fetchErr)
        return []
    }
}

Update

func updateMember(member: MemberCDModel, image: UIImage?, teamId: Int16, name: String, github: String, age: Int16, location: String, position: String, yearsInHipo: Int16) {
    if let image = image {
        member.imageData = image.jpegData(compressionQuality: 0.5)
    }
    member.team = fetchTeam(id: teamId)
    member.name = name
    member.github = github
    member.age = age
    member.location = location
    member.hipo?.position = position
    member.hipo?.yearsInHipo = yearsInHipo
    
    saveContext()
}

Delete

func deleteMember(member: MemberCDModel) {
    context.delete(member)
    saveContext()
}

Sorting

Rules
1- By using the extension function you wrote, find the most occurences of the character for each string in the array and sort in descending order.
2- If two or more strings contain the same amount for the character, sort these according to their length.
3- If two or more strings contain the same amount for the character and have the same length, sort these in alphabetical order.

fileprivate func sort(members: [MemberCDModel], character: String) -> [MemberCDModel] {
    var sortedArr = members
    sortedArr.sort(by: {
        let lastName1 = $0.name?.findLastName() ?? ""
        let lastName2 = $1.name?.findLastName() ?? ""
        if lastName1.countNumberOfOccurrencesOfCharacter(char: character) != lastName2.countNumberOfOccurrencesOfCharacter(char: character) {
            return lastName1.countNumberOfOccurrencesOfCharacter(char: character) > lastName2.countNumberOfOccurrencesOfCharacter(char: character)
        } else if lastName1.count != lastName2.count {
            return lastName1.count > lastName2.count
        } else {
            return lastName1 < lastName2
        }
    })
    return sortedArr
}
