remove NIL values and partcial match from array

Question

I have an Array of JSON Data that I want to delete nil objects and I have one object with the word Connex in a long string that I want to delete. This value is in the $0.financialInstitution field.

I've tried using filter to find the items I want to delete. My JSON data is rendering correctly.

I've tried working with the solution on this post: Check if array contains part of a string in Swift?

I get an error: Cannot convert the value of type '(String) -> Bool' to expected argument type '(RateDetail) -> Bool' when I change the array to use my JSON data.

 // to remove / surpress nil values 
    let nonNilElements = rateDetails.compactMap {$0}

 // this does not work


 //code form post noted above, updated with my search parameters 
and array

    let itemsArray = rateDetails
    let searchToSearch = "Connex"

    let filteredStrings = itemsArray.filter({(item: String) -> Bool in

        let stringMatch = item.lowercased().range(of: searchToSearch.lowercased())
        return stringMatch != nil ? true : false
    })
    print(filteredStrings)


    if (filteredStrings as NSArray).count > 0
    {
        //Record found
    }
    else
    {
        //Record Not found
    }

Value in RateDetails

.RateDetail(financialInstitution: "Your Neighbourhood C.U.", variableRate: "0", sixMonths: "0", oneYear: "3.59", twoYear: "3.69", threeYear: "3.79", fourYear: "3.89", fiveYear: "3.99", date: "2019-07-01")

value to be deleted:

RatesJSON.RateDetail(financialInstitution: CANNEX on June 30, 2019 at 00:30:20 ET", variableRate: "0", sixMonths: "0", oneYear: "0", twoYear: "0", threeYear: "0", fourYear: "0", fiveYear: "0", date: "2019-07-01"),

Blank value to be deleted:

RatesJSON.RateDetail(financialInstitution: "", variableRate: "0", sixMonths: "0", oneYear: "0", twoYear: "0", threeYear: "0", fourYear: "0", fiveYear: "0", date: "2019-07-01")

I want to delete array values that are blank
delete the value connex that is part of a longer string stored in the financialInstitution field.

and can you give us some example of what exactly is the output? Like this, it will be easy for me to help you. — m1sh0, Jul 01 '19 at 13:41

Is itemsArray an array of RateDetails?

If so, your filter closure states that each item in the array is a String, which isn't true. It's a RateDetail.

So the correct closure looks like this:

itemsArray.filter({ (item: RateDetail) -> Bool in
...
})

just as an adding on this answer can be that in the filter function item.financialInstitution should be checked for an empty value and for "CANNEX" – m1sh0 Jul 01 '19 at 14:11

I do not know if I managed to understand you, but try something like this...

let resultArray = rateDetailArray.filter { rateDetail in
 return  !rateDetail.financialInstitution.isEmpty && !rateDetail.financialInstitution.lowercased().contains("Connex")
}

Thank you. I have this a try and the empty values have been removed, but CANNEX is still showing. I copied and pasted part of the string from ratesDetails to remove the risk of typing errors. – k.thomas Jul 01 '19 at 15:10
